The electrophysiology of voluntary and cued language switching: evidence from event related potentials and neuronal oscillations

The language control processes used by multilinguals to monitor and control their language use are commonly investigated in the lab using picture naming paradigms in which participants are instructed when to switch between languages. However, …

Are alpha and beta oscillations spatially dissociated over the cortex in context-driven spoken-word production?

Alpha- and beta-band oscillatory power decreases have been consistently found in spoken-word production, and localized to left lateral-temporal and lateral-frontal lobes (e.g., Piai et al., 2015; Roos & Piai, 2020). These oscillations have been …

The Diagnostic Value of Language Screening in Primary Progressive Aphasia: Validation and Application of the Sydney Language Battery

Purpose: The three variants of primary progressive aphasia (PPA) differ in clinical presentation, underlying brain pathology, and clinical course, which stresses the need for early differentiation. However, brief cognitive tests that validly …

Disentangling language production impairments in Parkinson’s Disease

Parkinson’s Disease (PD) is a neurodegenerative disorder characterized by cardinal motor symptoms, including resting tremor, rigidity and bradykinesia, and cognitive impairments, such as deficits in executive function, attention and short-term …

Neuroimaging evidence for shared lemma representations in speech production and comprehension

Lemma representations are thought to map the meaning of words to their sounds and vice-versa (Levelt et al., 1999). There is evidence using different methodologies that suggests that lemmas are localised in the middle portion of the left middle …

Neural oscillations in the aging brain associated with interference control in word production

Speaking is not only about retrieving words and structuring them into sentences, but it also requires top-down control to plan and execute speech. In previous electrophysiological research with young-adult speakers, mid-frontal theta oscillations …

Electrophysiological signatures of conceptual and lexical retrieval from semantic memory

Retrieval from semantic memory of conceptual and lexical information is essential for producing speech. It is unclear whether there are differences in the neural mechanisms of conceptual and lexical retrieval when spreading activation through …

The effect of deep brain stimulation of the subthalamic nucleus on language function in Parkinson’s disease: A systematic review

Purpose: This systematic review focuses on the effect of bilateral Deep Brain Stimulation (DBS) of the Subthalamic Nucleus (STN) on language function in Parkinson’s Disease (PD). It fills an important gap in recent reviews, by considering other …

Mediated phonological-semantic priming in spoken word production: evidence for cascaded processing from picture-word interference

The cognitive architecture that allows humans to retrieve words from the mental lexicon has been investigated for decades. While there is consensus regarding a two-step architecture involving lexical-conceptual and phonological word form levels of …

Effects of transcranial magnetic stimulation over the left posterior superior temporal gyrus on picture-word interference

Word-production theories argue that during language production, a concept activates multiple lexical candidates in left temporal cortex, and the intended word is selected from this set. Evidence for theories on spoken-word production comes, for …
